This is impossible due to how the Fedora and RHEL releases align, and it is
impossible to change that given RHEL's QA requirements.
When an RHEL release m based on Fedora n gets released, Fedora has long
since moved on: Not only will Fedora n+1 be either already out or around the
corner (and thus likely out by the time CentOS releases), but even Fedora n
updates will now contain packages newer than RHEL m! (Heck, even Fedora n-1
updates will!) RHEL does not include all the post-release version upgrades
of the Fedora version it's based on. Some packages in RHEL m might even be
newer than in Fedora n (backported from Fedora n+1 or even n+2), but others
will be older, and never get upgraded in the lifetime of RHEL m. (RHEL's
update policy is, by design, much more conservative than Fedora's, even the
new one.)
So it is not possible to move from Fedora to RHEL (or equivalent) without
downgrading some packages, and I don't see any way to change this. (It
definitely can't be changed on the Fedora side. It could theoretically be
changed on the RHEL side by backporting all the version upgrades from Fedora
n into RHEL m, but I don't think that would fit the RHEL customers'
requirements, so I don't see Red Hat allowing that, ever.)
